Whats your price range?
I went thru scope after scope years back and decided for my money Leupold was THE scope. most of my handi's wear them VXII and a couple M8's.
A couple of the guys on here convinced my the quality of the cheaper scopes have come up in recent years. After purchasing a couple I agree they have come along, still not to the Leupold's but not at there cost either. There is a couple I liked for about 100beans.
Lower end Nikon on sale can be had for just over the 100 mark.
I have three PENTAX scopes that I really like, also but need to be fixed power to keep at/ just below the $100. Also the variables tend to have less light gathering. So you may be better with the fixed power anyhow with them.
As for the rings, i prefer the Leupold as well PRW and the QRW's are TOP NOTCH!! I have also had good luck and fit with the older 4x4 rings from Weaver. Burris "ZEE" are popular and all steel. I used to really like them but the had problems with quality control some years back. they wouldn't fit all weaver bases and required "tweaking" sometimes this resulted in broken rings. Also they stuck to a archaic screw diameter that liked to strip. So I abandoned them. This was a couple years back, so possibly fixed now.
Good luck and let us know what you get and how you like it!!!
